The voltage induced in the coils are proportional to the rate of turn of the vessel or vehicle such as a towboat utilizing the rate of turn indicator 10. The bridge rectifiers 63 and 65 rectify the coil voltage to a DC voltage to operate the rate of turn meter.. Field of the Invention. The present invention relates to a navigational aid or nautical instrument, and more particularly, pertains to a rate of turn indicator for indicating the rate of turn from a course of travel for a vessel or other like vehicle.
3. The apparatus of claim 1 and in addition a support for the rate-of-turn sensor, said support being adapted to be fixedly attached to the ship and having adjustment means for the plane of the rate-of-turn sensor. 4. rate-of-turn sensor, said sensor being mounted in a fixed position relative to the ship's structure with its response axis parallel to the vertical axis of the ship and generating a signal representative of the rate-of-turn of the ship,
